<em><strong>Minimize redirects</strong></em>

<strong>Remove the following redirect chain if possible:</strong>

Should we do something? Have we set something wrong?

Thank you

Hey @surname – thanks for your message.
Please note that these issues aren’t related directly to ShortPixel but to Autoptimize plugin which includes image optimization offered by ShortPixel.

Please contact support @ Autoptimize and ask for further assistance on this.

Thank you,
Alex

Optimizing Matters

No worries @surname , optimizingmatters goes where it is needed 😉

So what you’ll have to do is exclude the revslider dummy img from optimization, using this code snippet;
```
add_filter('autoptimize_filter_imgopt_noptimize','imgopt_excl');
function imgopt_excl() {
    // return a comma-separated list of images to exclude
    return 'revslider/public/assets/assets/dummy.png';
}
```
For the “identical content” one; that’s because image is not optimized when used in revslider, you could change the URL in the slider to the shortpixel one OR add flores-bach-2.png in the code snippet above (making it 'return 'revslider/public/assets/assets/dummy.png, flores-bach-2.png'; ).

For the sprites proposal; you will very likely receive a similar warning when those images are not optimized, this cannot be solved in AO.

For the redirect; you seem to have exceeded the free threshold for image optimization on that domain, you’ll have to either disable image optimization there are associate the domain with your shortpixel account (and make sure there are credits available).

hope this helps,
frank

Hi Frank
```
add_filter('autoptimize_filter_imgopt_noptimize','imgopt_excl');
function imgopt_excl() {
    // return a comma-separated list of images to exclude
    return 'revslider/public/assets/assets/dummy.png';
}
```
It worked perfectly, thank you very much!
